1 Claim. (Cl. isle-16) My present invention relates to improvementsments for the toaster. Suitable frames I6 are also in toasters. It hasbeenmy object to provide secured to the end wall I and top wall II of ain a toaster, which has automatic means for endsize to receive the breadto be toasted, which ing the toasting operations, simple means forframes I6 are spaced to enter between the frames setting theorganization for accomplishingits I4 when the end wall I0 and top wallII are 6 cycle of operations, and I have shaped and arswung into ClosedpositiOIlranged the divers elements going into the con- TO time thetoasting operation I emDlOy a Cylinstruction of thetoaster so that theseelements der I1 mounted substantially centrally of the can beeconomically produced and assembled to base 5 in Which Cylinder iS apiStOn I8 yieldngly secure a toaster of dependable operation and pressedtoward the inner end of the cylinder by 10 sturdy construction andcapable of long usefula coil spring I9. The piston rod 20, extendingness, Y from the piston I8, as most clearly shown in Fig. I haveillustrated my invention in connection 2, has the outer end thereof,which extends with a toaster of what may be called the oven through theinner end of the cylinder, bent at 90, type, as shown in theaccompanying drawings, which bent end extends through a slot 2| pro- 16in whichvided in the flange of an angle plate 22, the other Fig. 1 is aside elevation of a toaster embodyflange or web whereof is secured tothe bottom ing my invention with the bread holding element side of thetop of the base 6.

The lower compressthe spring I9 when the handle 26 has end of the end wall I 0 is pivotedto the base 6 between the side walls a in such a. manner that gdgos faras t nu go 1n an anti'clock' when the end wall I0 is swung into verticalposi- Pivoted to rotate about the shaft 25 is a plate f W th t i5 tionthe top wall II w1ll extend bet een e op 29 the end hereof opposite tothatpvot to f the end wall I0 and the top of the end wall 9.

Frames I4, as mostclearly shown 20 S0 that When the DSOII i8 mOVeS beyOnd the in Figs. 2and 5, are secured between the side aperture 24 and is thrown forward bythe spring 50 walls 8 in spaced relation so as to receive a slice I9 theturned end portion of the piston rod 20 of bread to be toasted betweensuch frames, and engages the downwardly bent end of the plate up anddown between the top and bottom plates 29 and throws the same upwardly.of the frames I4 are arranged suitable coils I5 of Secured tothe plate29 is a stud bolt 30 which resistance metal which constitute the heatingeleextends upwardly through a perforation pro- 55 vided in the top wallof the base 6. The upper end of the stud bolt 30 is bent at right anglesand is proportioned to come closely adjacent to an edge of the frame I6when the plate 29 is in its lowermost position and the frame I6 closedwithin .the oven portion of the toaster.

Secured to and depending from the pivoted end wall I is an arm 3|. Thearm 3l extends through a. slot in the top of the base 6. 'I'hrough thearm 3| is arranged a pin 32 about which pin is coiled a spring 33, theends whereof are disposed to engage the lower face of the top of thebase 6 as the end wall I 0 approaches its fully opened position. Thisarrangement secures the cushioning of the opening portion of the ovenwhen it is approaching its fully opened position.

The operation of my toaster is as follows: After the heating elements I5have been connected with a source of current supply through the leads34, slices of bread are inserted in the frames I6 and the swingoutportion of the oven, consisting of the end wall I0 and top wall II aremoved into closed position. The handle 26 is then rotated into ananti-clockwise direction as far as it will go, which effects through thecrank arm 21 and link 28 the movement of the piston I8 so as to compressthe spring I 9. The atmospheric pressure of the air maintains the pistonin its inward position and the spring I9 under compression until airenters behind the piston through the needle valve 23. This needle valvecan be set so that the flow of air therethrough can be entirely stoppedor regulated to pass any amount of air, thereby permitting the apparatusto be easily adjusted for toasting stale or dry bread or freshly bakedor moist bread and to any degree of brownness which the operator maydesire. After such amount of air has entered the cylinder through theneedle valve 23 as to permit the piston I8 to pass beyond the aperture24 the spring I9 is relieved from atmospheric impediment and moves thepiston quickly forward, thereby projecting the turned or bent end of thepiston rod against the downwardly bent end of the'pivoted plate 29,thereby forcing theplate 29 upwardly and the stud bolt 30 carried by theplate 29 is projected against a portion of the frame I6 which causes thepivoting of the end wall I0 to which is attached the top wall II andframe I6 into the open position most clearly shown in Fig. 1.

No nicety of adjustment of the needle valve 23 is required in the usualoperation of my toaster, but it is possible to adjust the needle valveto any degree of nicety, thereby securing a timing of the action of thedevice which will suit the most critical of operators. All that isrequired in the use of my device is the insertion of the bread, theclosing of the oven and the setting of the handle 26. The parts are fewand simple. There is nothing to get out of order and the toaster isextremely efficient, owing to the fact that all the heat generated isclosed within the oven during the toasting operation.

Having described my invention what I claim as new and desire to secureby Letters Patent is: A toaster comprising a compartment having apivoted closure, heating elements arranged in spaced relation withinsaid compartment, bread holding elements spaced to enter between saidheating elements secured to said pivoted closure, means for opening saidpivoted closure comprising a rotatable shaft, a handle for rotating saidshaft, a crank arm fixedly carried by said shaft, a link pivoted to saidcrank arm, a guide for said link, a cylinder, a piston therein, a springfor urging said piston in one direction, a valve for admitting air tosaid cylinder to control the action of said spring, said cylinder havingan aperture to release the control of said spring adjacent one end ofthe movement of said piston, a piston rod bent at right angles andhaving the right angled end thereof secured to the guided end of saidlinkI and means operable by the bent end of said piston rod for movingsaid closure into open position.
